Adiadochokinesis

Dysdiadochokinesis is the inability to execute rapidly alternating movements, particularly of the limbs. It is most readily demonstrated by asking the patient to pronate and supinate an arm at speed, with a tap on the opposite forearm at the extremes of movement.

Ipsilateral to the side of a cerebellar lesion, the hand shows the classic slow clumsiness of dysdiadochokinesis.
